Dolphins DE Hayes to miss rest of season with torn ACL
Hayes was hurt when he sacked Oakland's Derek Carr during Miami's 28-20 victory Sunday.
"He was trying to not put body weight on the quarterback," coach Adam Gase said Monday. "His foot got caught in the ground."
Hayes leads the Dolphins with two sacks. His loss is costly even though the front four was the Dolphins' deepest area.
"He's one of our leaders and best run defender," Gase said. "That's going to be a tough one for us to swallow.
The loss of Hayes, Branch and defensive tackle Akeem Spence, who was ejected, left Miami with only six defensive linemen. Offensive tackle Jesse Davis filled in as an emergency defender during a goal-line situation.
